This Phase Three contributed an additional 7,500 km2 of high-quality 3D data, building on the 9,500 km2 previously acquired, bringing the total regional multi-client library to over 17,000 km2 of wide-tow 3D seismic coverage.

The acquisition was performed by Shearwater‘s SW Empress vessel.

With completion in line with the planned late Q1 2026 timeline, decision-ready data is expected to be available to the industry in the first half of Q2 2026.

According to the Norwegian company, this marks the conclusion of the third acquisition season.

“The Pelotas Basin continues to attract strong industry attention due to its geological connection with the prolific Orange Basin offshore Africa. This conjugate margin relationship enhances the exploration potential on the South American side,” Shearwater said.
